One day the sun will die

[MagentaRocks]

For some reason I wondered what would happen if the sun dies. I looked it up and it turns out that the sun is half way through its life and it will die, by getting hotter and burning itself out in effect. It will also swallow the earth. It is likely to be a billion years before life on earth is wiped out - as the sun gets hotter the water around us will boil etc but it feels really weird to think that one day there will be nothing and no life anywhere.

I think I have freaked myself out during lockdown!

FFS! Stop being so depressing!

I can hardly wait...

There's a giant asteroid due at the end of the month. It's not supposed to hit us, but then three months ago, everyone was saying some virus in China was just a storm in a teacup...

Come on, OP. Step up your game. You’re being out-doomed here.

I have a bad feeling about that asteroid.

Why? Have you got cosmic insights?

Yeah still waiting for the 2011 asteroid to hit.. and the one from 2014..

They are in the queue.

Don't worry OP, Nibiru will get us long before the sun dies

Don't forget about the fires nearing Chernobyl !

I live in Scotland I'd like it if the sun warmed up a little but perhaps not to that extreme 😆

On the upside I guess we'll be one of the last to go ....

Why is it depressing. The whole concept of space, the universe is fascinating. I don't see what is wrong in discussing it.

I think a few people have misunderstood the tone of your thread OP

You are only just discovering this now? Weren't you taught about this type of stuff at school? That is what fascinates me about this conversation...

Anyway, stars die, life on this planet will end at some point. It's all a perfectly natural life circle.

This article addressing the current state of the planet is a more of a pressing concern for me.

Ps: this is a montessori elementary teaching chart which demonstrates the size of the earth and the sun comparatively.

I have drawn an arrow to help you spot the earth.

Of course we learnt this sort of thing in school - a very long time ago. But it isn't some thing you think about day to day

I don't often start threads and this is why - people ridiculing and pissing on your chips for starting a discussion. I just thought it was something a bit more interesting to talk about that isn't about covid and who is breaking lockdown rules.

When the sun dies and the entire planet has been vaporised, somewhere in the ether there will still be someone furiously bashing out a post on Mumsnet about how lazy teachers are, how changing your sheets anything less than once a day is 'minging' or how reckless it is to leave your child in the car to go and pay for petrol.

I guarantee it.

Do you have a sandwich board with “The End of the World is Nigh” on one side and “‘Tis the End of Days” on t’other OP?

Are you good mates with all four horsemen of the apocalypse too? I’ve heard they are a really good laugh down the pub after a hard days apocalypsing.

Reminds me of the intro to one of Bill Baileys stand up shows OP:

"Of course, the universe is gradually slowing down and will eventually collapse inwardly on itself, according to the laws of entropy, when all it's thermal and mechanical functions fail, thus rendering all human endeavors ultimately pointless. Just to put the gig in some sort of context."

This isn't quite what Sunshine is about; it's something theoretical that could happen at any time and eat the sun from the inside out.

Space is not infinite. We've got a pretty good outer limit for the size of the universe and a few models to suggest what happens next (Big Crunch etc). There are probably other sentient beings out there wondering the same things as we are.
We've got about 5 bn years until the sun gets to red giant state, at which point it will engulf Mercury and Venus, and probably Earth. Life on Earth will then be destroyed. Then it will contract back to a white Dwarf star, but it will do a load of other phases on its way, growing larger and brighter before shrinking.

Jupiter is a failed star That's mean. Jupiter tried it's best!

There is a really good Doctor Who episode about this. The National Trust preserved the Earth for as long as they could but, y'know, budgets..

there will still be someone furiously bashing out a post on Mumsnet about how lazy teachers are, how changing your sheets anything less than once a day is 'minging'

I believe the correct mn terminology is 'grim' 😆

Not ridiculing but genuinely agog that this is a genuine thought you have just had today (esp if you went to school such a long time ago).

So, another genuine question.

the technology that you previously mentioned that may step in and save humanity, how will it be powered?

@flippefloppe cold fusion, obviously
